The Refund operation must be done using the Transaction ID of a successfully completed transaction.
The Refund operation, as its name states, consists of returning the money already collected by a Payment or a Capture transaction.
The amount collected can be refunded in total or partially. You cannot refund amounts bigger than the one sent in the original transaction.

Note

• You can perform multiple refunds until you reach the total amount of the original Payment and your balance in the system is sufficient.
• A refund will be done via a SEPA Credit Transfer to the account information provided by the issuing bank. It is not possible to refund to other accounts.
• Refunds can be bounced by the receiving bank in case of restrictions on the receiving account (i.e. Depot or Savings accounts).
• Created refunds will be "Pending" (code=0) until they are collected and processed at 05:30 (Europe/Amsterdam), before that time a refund can still be cancelled.
